To lock the vehicle you must supply a negative (-) pulse to the LOCK WIRE while interrupting
the DOOR LOCK DETECTION WIRE with a relay. To unlock the doors, you must provide a (-)
negative pulse to the UNLOCK WIRE and the DOOR LOCK DETECTION WIRE using two
diodes to isolate them. The lock/unlock wires are driver and passenger door key cylinder wires.
This interface must be done inside the driver door or passenger door between the ECU and
door lock actuator.
